Ken Kramer, a researcher with the Citizens Commission on Human Rights of Florida, says the numbers underestimate the extent of the problem, because medical examiners do not track deaths attributed to antipsychotic drugs or to antidepressants, both of which carry black-box or black-label warnings. The warnings on antidepressants, required by the Food and Drug Administration, state that the drugs increase the risk of suicidal thinking and behavior in children, adolescents and young adults up to age 24. (Antidepressants include Paxil, Prozac, Zoloft, Effexor, Lexapro and Celexa.)
